I have found that many of the brake parts will have a multi year run. For example, 1955 car rear wheel wheel cylinders with work on a 1954 car. The lines to the cylinder are different, requiring different lines, but they can be made to work. And 1955 car rear wheel cylinders are very inexpensive.
I like NAPA or older "Mom and Pop" type auto supply stores that have the old catalogs and will take the time to look items up for you. There are still some stores out there like that and. I think, those stores are the key to finding your parts.
